Sweet and juicy watermelons do not ripen after they are picked from the vine.
This increases the risk of buying an unripe fruit, despite its external attractiveness.
To avoid disappointment and choose the right watermelon, biologists advise following useful rules. ResearchGate reports the details.
Rules for a ripe watermelon
Experts advise following useful tips that will make it easier to choose a ripe watermelon, and you will definitely not be disappointed.
First, start by taking a good look at the watermelon.
As the fruit ripens, the skin changes color from shiny to matte. Accordingly, avoid fruits with a strong shine.
Secondly, a light spot always forms on the rind when it touches the ground. A well-ripened fruit has a spot of a deeper yellow color.
Third, always judge a watermelon by weight. A ripe fruit should be heavy for its size and have a sweet aroma.
Also look for small, dry spots on the rind - this is a good sign of sweetness.
Impact test
An effective way to determine ripeness is sound.
Simply tap the watermelon lightly with your fingers to determine if the fruit is ripe by the tone of the sound.
You need to choose a watermelon that resonates and has a metallic, dull sound.
